Description de Produit

Product Description

 

Ferrous Sulfate Heptahydrate, the color of ferrous sulfate heptahydrate is green, monoclinic crystal or particle, no odor, relative density 1.898, melting point 64ºC. Easily soluble in water, (48.6g/100ml water at 50ºC) red heat decomposition to form ferric trioxide, soluble in glycerol, insoluble in ethanol, corrosive, in dry air will be weathered. At 56.6ºC, the heptahydrate is transformed into tetrachlates, and at 64.6ºC, it becomes monohydrate. At 90ºC, six crystalline water is lost, and at 300ºC, all crystalline water is lost to form anhydrous substance. At red heat, SO2 and SO3 are decomposed and released. It's corrosive. It fluoresces in dry air. The anhydrous substance is a white powder, but when it is mixed with water it turns blue-green.

Application

(1)Water treatment
Ferrous sulfate is used for flocculating and purifying water, and removing phosphate from urban and industrial sewage to prevent eutrophication of water bodies.

(2) Reducing agent
A large amount of ferrous sulfate is used as reducing agent, which mainly reduces chromate in cement.

(3) Colorant
The production of a tannic acid inks and other inks requires ferrous sulfate. Ferrous dye is also used in wood dyed mordant.Ferrous sulfate can be used to stain the concrete into yellow rust, and woodworking ferrous sulphate make the maple dye silver color.

(4) Analytical Chemistry
Ferrous sulfate can be used as a reagent for chromatographic analysis.
